It is distinct from the signal itself, (e.g. a picture of a waveform on screen and its zoom ratio) and may not be directly related to a signal at all. A non-destructive editor is a good example of this concept. Generally we refer to an internal state of an editor as a result of a performance and a corresponding recording event.
